Application and February 3,1906. seen No. 299,321,

To alt whom it may concern: Be it known that l, HARRY M. PFLAeEn, .a citizen of the United States, residing at St. Missouri, have invented Draw-Bar Pocket for Car-Body Bolsters, oi. which the followin is'a specification.

My invention re atesito a combined brace or filler and draw-bar pocket specially designed for the ordinary class of car-body bolster which is built up of top and bottom plates, having the center plate,-side bearings, and thimbles attached thereto, and has for its object to enable the draft-gear,-preferably that for which I have obtained Letters Patent in the United States dated January 10,

1905, No. 779,559, to be applied toold'cars which are fitted with this class of bolsters and nowin use, whereby the strain of the draft gear is transmitted by the pocket and bolster to all the longitudinal sills of the car, the strength andrigidity of the bolster increased, andthe ordinary draft-timbers eliminated. 1The invention consists in features of nov- 6 W, reference being had to the accompanying drawings, forming part of this specification, whereon Figure 1 is a side elevation of a car-body bolster of the class described havingrny im proved brace and combined draw-bar pocket (seen in end elevation) applied thereto; Fi 2, a similar View, to enlarged scale, of the bo lster broken away and showing the pocket with the inclosed draft-gear in cross-section on line 2 '2 in Figs. 3 and 4; Fig. 3, a crosssection through the bolster and brace vertical lon itudinal section through the pocket and draftgear on line 3 3 in Figs. 2 and 4, and Fig. 4 a horizontal section through the same on line 4 4 in Fig. 3.

L'ike letters and numerals of reference denote like parts in all the figures.

' (1 represents an ordinary car-body bolster having the top plate 1, bottom plate 2, cen

ter plate 3, side bearings 4, and intermediate thimbles 4:,attached thereto in the usual r iell-known manner. Between the plates 1 and 2- at the middle portion of the bolster a on its upper side to as hereinafter described and claimed,. v

' through cored holes therei .8 and top wall and a 2 by rivets 5, which pass through the plates 1 and 2|and top and bottom flanges spectively, of the brace b.

From the front side of the brace ii and integral therewith projects a horizontally-ar-- ranged draw-bar pocket -c, which is closed at the top and open atthe bottom for the insertion therethrough of the operative parts of the draft-gear. The pocket c consists of two upright side walls 8 at a suitable distance apart and united to each other at the top by a horizontal wall 9, which is flush on the out,- side with the top ofthe bolster afand forms at its junction with the top. flange 5 .ol? the brace b a shoulder 9,.which overlapsgand bears against the front-edge of the top plate 1 of thebolster a, a similar shoulder 9 overlapping the lrontedge of'the bottom plate 2,. being formed at the bottom of, the pocket s between its sides 8. The wall 9 is'adapted bearat and adjaceutto the upright side walls 8 againstthe under 1 side of the middle longitudinal car-sills d,'to which the pocket 0 is firmly secured by the bolts 10; which preferably pass upward or in the sidewalls 9 and through the middle sills (E, as shown. Moreover, the brace t is, secured with the bolster a to the cansills d by bolts 10, which pass upwardthrough the 1 bolster a, brace b and sills d, the bolts 10 and the parts to the sills d for the entire length of the pocket 0 and width of the bolster a.

, The pocket :3 is specially adapted for receiving the draft-gear, preferably arranged and operating on the principle of that de scribed in the said Letters ,latent, and which in the present case consists of the-two fob lower-plates 11 and 12, with their "intermediate springs 13 arranged side by side in the same horizontal plane, the front followerplate 11 being operated in bulling by the rear end of the draw-bar 6, (broken away) and the back followenplate 12 in pulling by the yoke c ,which is integral with the draw bar e and straddles the back followe -plate 12, all the said parts of the dra -gear being inserted and assembled within the "pockets c through its bottom opening, as before mentioned. For'this purpose each side wall 9 of the. pocket r formed oil-the inside at its front and rear ends with an upright lug or shoulder S' 5*", respectively, the two opposite p 85. 10 thereby insuring a rigid fastening of all i f l'ont follower? pl ,gsame time transmitting the pulling and buff te a1 with the brace '15 and secured with the 1 b5;
